I'm switching back and forth between 1.2 and 2.0. No need to worry.
Ralf, on the same server machines - ie, switch off 1.2, start 2.0, or on different servers, one running 1.2, another running 2.0?
Of course on the same machine.
Fair enough. I was thinking of using 2.0 as a 'new system' during a general migration to both: (a) new server hardware, and (b) updated OS - not wanting to upgrade the OS in-situ with critical applications running
And, in your case, where are the user maildirs? On the same machines as the servers? Somewhere else?
In my case on the same machine, but since both 2.0 and 1.2 use the same setup, how does that matter?
I wouldn't start to guess - I know relatively little. But I was interested in your experience, and opinion; it's clear from many of your contributions that you're running some serious systems, and just thought to ask.
In essence, just trying to see if the co-existence principles, that the OP was thinking about, would help or hinder in the more general problems of migration of architecture, especially if the dovecot server were to be migrated elsewhere while leaving the maildirs 'where they were' and able to drop back to v1 in case of problems.
(Migration to different system arrangements is really a topic in itself, and I don't want to hijack this thread, just explaining what I was thinking around.)
Thanks for the reply, Ron
